Mold

There is mold on one or more of my vents.

Mold on your vents usually indicates the presence of mold in your ductwork. Duckwork starts at your air handler. You'll need to do the following:

1. Have your air ducts cleaned/sanitized.

2. Install a UV light in the air handler.

3. Have the air handler cleaned/sanitized.

There is mold on the outside of one or more of my vents.

Mold present on the outside of a vent indicates high humidity/moisture at that location. This can be caused by one or more of the following:

1.  Ductwork/boots that are not fully sealed at the vent, causing air leaks which produce moisture.

2.  Insufficient levels of insulation in the attic causing an inadequate barrier between the temperature of the conditioned air in the room and the temperature of the air in the attic, causing moisture.

3.  Air leaks in your ductwork causing moisture at the leaks.

4.  Mold in your ductwork.

Solution is to ensure all of your ductwork/boots are fully sealed, ensure your level of insulation in the attic is sufficient and to have a duct cleaning.

There is mold inside my air handler.

Mold inside your air handler can appear in your plenum, air filter, fan housing, blower wheel fins, evaporative coils, and/or on the insulation of the panels.

You will need to remove/sanitize as much mold as you can, install or add a UV light, and have duct cleaning.

There is mold somewhere else in my house.

Mold inside your home indicates a humidity/moisture problem. You will need to do the following:

1.  Have the mold sanitized and removed as much as possible.

2.  Make sure you have adequate UV protection in you air handler.

3.  Have a complete duct cleaning.

4. Consider adding a whole home dehumidifier to your HVAC system.

5. Consider upgrading your thermostat to one that can monitor your home humidity levels.

6. Consider purchasing a variable speed HVAC system.
